Introduction: obesity often leads to deregulation and disrupting of the function of adipokines, which leads to various altered conditions, including metabolic syndrome (MetS). Adiponectin is one of the main adipokines secreted by adipocytes. The ADIPQ gene polymorphism rs266729 (-11377 C>G) is significantly associated with metabolic alterations related to obesity in different populations. Mexico has a high prevalence of obesity and risk factors associated with MetS. We investigated the association of the ADIPQ gene polymorphism rs266729 (-11377 C>G) with MetS in a Mexican population of western Mexico. Methods: a total of 101 MetS patients and 70 unrelated healthy subjects were genotyped for ADIPQ polymorphism rs266729 using the restriction fragment length polymorphism method. Results: we found a higher frequency of the minor allele G in MetS patients, as compared to that observed in the control group (OR = 2.17; 95 % CI, 1.26-3.70; p = 0.003). Also, the GG genotype was significantly associated with MetS risk under codominant (OR = 4.0; 95 % CI, 1.32-11.71; p = 0.014), dominant (OR = 2.16; 95 % CI, 1.12-4.03; p = 0.018), and recessive (OR = 3.33; 95 % CI, 1.14-9.45; p = 0.033) genetic models. Conclusion: our findings suggest that the minor allele G in the ADIPQ gene polymorphism rs266729 constitutes a risk factor for the development of MetS in a Mexican population of western Mexico.
